Dear Hiring Manager.
Thanks for your job posting.
I read your job description carefully and I think I have enough skill and experience to your job.
I have rich experiences in Objective-C & Swift for over 6+ years and have been developing a lot of iOS Mobile Apps successfully for my clients.
Now I mastered all kind of iOS Frameworks and Libraries, UI Animations, UIStoryboard + Auto-Layout as well.
I really hope to work on your project.
Thanks.
Best regards, Xin
